The median salary of a man in Alabama averages out at $44,567, whereas a woman's median salary clocks in at $31,674.

Alabama is one of only five states that has no equal pay laws at all, along with Mississippi, South Carolina, Utah and Wisconsin.

A myriad of factors affect the amount of income people earn, but even with those factored in, women make a significant amount less than their male counterparts, according to a study completed by the American Association of University Women.

According to the study, the smallest pay gap is in Washington, D.C., where women get paid 90 percent of what men make.

The widest pay gap was found in Wyoming, where women make 60 percent of what their male colleagues make.

Some of the factors that play into the gap include job choice, with women more likely to be teachers.

Parenthood also plays a role.

The study found that 10 years after graduation, 23 percent of mothers were out of the workforce, and 17 percent worked part time. That contrasts fathers, with 1 percent out of the workforce, and only 2 percent worked part time.

Even with those factors, much of the gap is unexplained.

"This leaves us with possible explanations that range from overt sexism to unintentional gender-based discrimination to reluctance among women to negotiate for higher pay," according to American Progress.

A bright spot in the study found that gender segregation has decreased over the last 40 years, with women venturing into typically male-dominated professions more and more.
